Warning: Spoilers for season one of Netflix's "Stranger Things" below.

It was the question looming over the season-one finale of "Stranger Things": What happened to Eleven?

Everyone's current favorite girl with telekinetic abilities (especially if Halloween is any indication) disappeared when she took care of (or did she?) the monster terrorizing the Netflix show's characters, possibly to another portal. Or she could be dead.

Now TVLine reports that actress Millie Bobby Brown is definitely returning as Eleven in the second season of the hit show, and "all signs point to her once again being a series regular," according to the outlet's sources.

Season two of "Stranger Things" will arrive sometime in 2017, and the show's creators, the Duffer brothers, have promised it will delve more deeply into the mythology behind the plot.
